# basis_universal
-Basis Universal GPU Texture Compression Codec
+Basis Universal GPU Texture and Texture Video Compression Codec
-Basis Universal is a ["supercompressed"](http://gamma.cs.unc.edu/GST/gst.pdf) GPU texture compression system that outputs a highly compressed intermediate file format (.basis) that can be quickly transcoded to a wide variety of GPU texture compression formats: PVRTC1 4bpp RGB, BC7 mode 6 RGB, BC1-5, ETC1, and ETC2. We will be adding ASTC RGB or RGBA, BC7 mode 4/5 RGBA, and PVRTC1 4bpp RGBA next. Basis files support non-uniform texture arrays, so cubemaps, volume textures, texture arrays, mipmap levels, video sequences, or arbitrary texture "tiles" can be stored in a single file. The compressor is able to exploit color and pattern correlations across the entire file, so multiple images with mipmaps can be stored very efficiently in a single file.

The system's bitrate depends on the quality setting and image content, but common usable bitrates are .3-1.25 bits/texel. .basis files are typically 10-25% smaller than using RDO texture compression of the internal texture data stored in the .basis file followed by LZMA. The current system is what we've been calling the "baseline" system, which is designed to reach all the GPU formats. The next major step is to extend the system to allow for much higher quality for the ASTC and BC7 texture formats.

So far, we've compiled the code using MSVS 2019, under Ubuntu x64 using cmake with either clang 3.8 or gcc 5.4, and emscripten 1.35 to asm.js. (Be sure to use this version of emcc, as earlier versions fail with internal errors/exceptions during compilation.) The compressor uses OpenMP for multithreading, but if you don't have OpenMP it'll still work (just much more slowly). The transcoder is currently single threaded (and doesn't use OpenMP).
-**Important:** I've changed the .basis file format today (4/7/19). The format should now be hopefully stable unless bugs are found.
+Note: The video branch contains many important optimizations for videos, such as P-frames with conditional replenishment (CR) support and I-Frames. We'll be merging this branch into master in a week or two, after testing. One expected use case for Basis texture video are for highly dynamic UI's written with WebAssembly and WebGL which need to display many dozens (perhaps a few hundred) smaller (preview) videos simultaneously with low CPU overhead. Modern video codecs won't perform well in WebAssembly until it supports [SIMD](https://www.chromestatus.com/feature/6533147810332672), so texture video can be usable where regular video wouldn't. Texture video costs more bits, but has very different tradeoffs vs. traditional video codecs.
